Good on you for learning about your firearms. I think every person should know every precise detail about each of their firearms and how they function.
@@deucedeuce1572 I love taking my guns apart and learning how they work. It’s a bit intimidating when it’s something new to the market and no one has instructional videos. I just started my journey in the firearms world a few years ago. Couldn’t imagine how difficult it was before UA-cam.
Thanks for being so thorough. I was able to disassemble my P3 thoney. I really enjoyed the way. You explained everything very detailed much appreciate it. Thank you again.
Amazing. As someone who loves to read textbooks, I thoroughly enjoy your videos. Great explanations such that I can just listen and casually look up to reference your video when needed.
Impressive camera work and the white background adds that extra added touch of contrast👍🏽 Perhaps some of your same handy work on the 365’s, Hint Hint… Keep up the great work, THANK YOU!!!
Compliments on the 320 series. It helped me a lot. Very well made content! Although it would be nice to see a detailed video of the maintenance (cleaning/ lubricading) process.
can't wait for your sights video, i just got a front sight stuck in my slide trying to hammer it in with a brass punch....now all my brass punches are deformed and i have a partially stuck sight haha
Love that shake fire ! Anyone can make a drop fire gun, but the holster fire is better and the shake fire is best ,the insta rust is also a great idea.
Whoa...so glad I found this channel! Very informative content and it was shot so clearly. I've owned 320s since before the upgrade, and I wish I found this channel way back when...glad to have it now though as I clean and inspect my latest purchase, a new to me XFull RDX.
Thank you! The channel has only been up and running for one year. I hope that in the coming years I can do the same educational videos for all Sig firearms. Glad to have you with us! Let me know if you ever need help or have questions.
Another great informative video on the Sig P320, your videos are simply the best, you do and explain the process exactly as it should be did. Do you think you'll be selling any of your videos, like in a part by part series or like a 4 disc set?? I would really be interested in purchasing it if you did. Your videos would be an absolute awesome learning process for anyone thinking about getting into gunsmithing as a career. And thanks again for taking the time to do the best vidoes ever on the Sig P320 platform.
@Eugene Asher. Good to have you here and thank you for your kind words! I don't think I would ever sell this information. I started doing this for the purposes of giving something back to the firearm community who has guided and educated me for so long. Although, I do appreciate you considering what I have done valuable enough pay for it! To your question however, I believe that there is a method to download UA-cam videos (although I've never tried myself), which you can then throw onto a USB or other device. Perhaps someone here can comment on this or a quick Google search may solve it.
Great video, thanks. You mentioned nothing about cleaning or lubricating. Obviously if I’m going to take it down like this I’m going to clean everything while it’s apart. What parts and pieces need lube or does it need to stay dry? Thanks again for your time making this great video
Thank you. No, not a technical writer but I did do some research to look at how this sort of information is usually presented from companies like Microsoft. This was a bit of a undertaking but with the right method it becomes easier to consume this much data/process.
If the small internal striker return spring wears and or fails to hold the striker to the rear away from the primer at the chamber facing……… This could be the spring reportedly blamed by Sig for the competition range holster incident by the experienced shooter complaint video of premature detonation between two range course strings. Possibly causing too much pressure on the primer from routine movement of the pistol during and after reholster of the weapon. Reported by witnesses to have occurred at rest several seconds after placing the pistol back in the holster.🤔🫣😳😬🙃 However the trigger bar flange would also still have to fail to continue to grip the sear ledge possibly from all the movement and vibration from operation detonation and recoil. Making the striker safety spring another suspect. Fracture of the large main striker spring could also be the alleged reported spring fail by Sig factory maintenance. 🤫🙄🤔 Sig has always been known as a design having very many springs since becoming popular 50 years ago. Regards and thanks for the informative videos.
Interestingly, enough many people thought the reset spring was the cause of that incident too, especially seeing as how the shooter mentioned that that spring was noted as a part that was broken when they submitted the gun to Sig, which made it sound like Sig admitted that it was the problem, when in truth, they likely told him it was broken and was replaced. What many people don’t know is that the reset spring was deleted/discontinued in the P320 by Sig in July 2020/2021, because it was deemed redundant. When the gun discharges the recoil of the slide will push the striker back and the striker will then catch the sear ledge on return forcing the reset anyway. I believe rather strongly that that particular issue was not due to a broken reset spring, all current signs indicate the trigger was pulled unintentionally. Mainly because if there was an alternate method to discharge, there should be a consistent and repeatable way to measure it (like the drop safety issue in 2017). I do believe it happened and I also believe people witnessed it, they however they did not understand the situation well. From an outside perspective it would look like an unintentional event, but they would not be able to see something as small as a fraction of an inch movement of the trigger being shifted by a piece of clothing especially when the trigger would be something semi concealed in the holster at that time. Of course that’s just a really long winded way of saying that, although I do believe these things, no one truly knows what happened and I am definitely open to changing my opinion if presented with scientific evidence of some sort.
@@SIGMECHANICS Always considered the original incident issues resulting in the drop test recall was rough handling, operator error by the shooters throwing their weapons around too much without proper respect or regard for common sense safety considerations. Now it seems obvious it has to be that, or a trigger/trigger bar to firing pin issue through the striker assembly. Which may have been addressed by the recall remedies. A manual safety similar to what the military decided with the 320 and previous 92F for recruits seems like a foolproof way to proceed. Unless condition 2 carry is the norm for all levels of Military experience, the practice has always been a ban on a round in the chamber until removing the weapon from the holster. Not to include the former Marines worked with for years who considered firing accidentally into a clearing barrel as an acceptable semi regular non reportable significant incident. Regards
If only I was as funny! Also, thanks! Glad I could bring something to the community that helps., the Sig community has been the most receptive and engaging group and I really enjoy making these videos.
Ah yeah. You know what, eventually I will have moved through all the SIG stuff, it’s not something I would do right away, but I wouldn’t rule it out eventually. I have been considering, focusing, mainly on modular type pistols, including those outside the Sig brand.
Sure thing. It’s the skeletonized Stainless extractor from LoneWolf. It’s been absolutely fantastic, it’s a non-MIM part and it’s easier to clean as it has a hole right through with rounded edges.
I know this is a old video and been watching all your videos. Very good and you explain everything really great. My problem hopefully you can help me with is the take down lever. Its almost impossible to turn. This is a original p320 updated by SIG but was always hard to turn it. Any ideas what I can do to fix it? I have watched other videos were they just flip it with there tumb. Any information would be greatly appreciated. Thanks
It’s most likely your guide rod and recoil spring. Make sure it’s properly seated on the barrel under lug. You can also try swapping to a 1911 style rod which should make it a bit easier depending on the spring weight.
@@SIGMECHANICS Greez thanks for the quick reply. Much appreciated. I will check the recoil spring first. New to pistols not fire arms. Really appreciate your quick response. Thank you. By the way your videos are top notch as many that follow you respond as well. Subscribed and look forward to more videos. Again thank you
It’s my absolute pleasure! Sometimes if your TDL is REALLY tight, you can always try to use a pair of pliers (assuming you can get good grip with the tight tolerance) and just pull the rod outward. This takes the pressure off the TDL and most certainly, the TDL will rotate more freely. Thanks for the kind words, let me know if there is anything else that comes up.
Hello, thanks for the video. Can you help me? I was cleaning my 320 and I found a tiny spring on the table that resembles the Striker reset spring in the video. I did have the striker out of the firearm to try and sop up some extra oil I accidentally got done in the striker channel. I did replace the reset spring into the striker and seated it as deep as it would go. My question is, seeing as how I never completely disassembled the striker do you think that reset spring will give me issues or am I good to go?
Send me a picture of the spring to sigmechanics@gmail.com and I’ll let you know. If it’s the reset spring, then you technically don’t need it because it’s a redundant part.
I’m trying to remove the optic cover on my M17 Commemorative. I removed the screw that holds the rear sight, however, the plate feels like it’s held by an additional screw. Looking in to the hole that appears to vent fouling or over pressure from the striker channel, appears to be a screw but I’m unable to confirm it’s a screw. I need to clean the fouling out. Otherwise, the plate it probably pressed in to the slide cut out. There’s another hole under the slide from the extractor channel.
If you look at the removed screws and see that they are intact (not broken off at the thread), there is a very good chance it’s dirty. Use a non-marring tool to see if you can wiggle it out.
What model do you have? The X5 comes with a 1911 style spring and rod. Standard models have what you see here. Personally, I use the 1911 type, but for this video, I opted for the standard, as most people would probably be used to seeing this.
You know which models require an Allen Wrench to remove the rear slide plate? Can they be replace with a regular one that don't need an Allen Wrench? (like the one in this video).
Thank you for a very detailed process . I just have one question if you can help. I have sig M17. Great shooter and used to be very accurate . However around 1800 rounds or so, the sight plate cover and the rear sight began to get loose. As you know the screws for the rear sight and the plate are inside the slide one is underneath the extractor spring . I tightened them and they became loose again this time felt down . The notorious small loaded chamber indicator spring got lost and I had to wait till my order of new ones arrived . I put locktite blue on the screws hoping they will not come loose again but now the site is not as accurate . My question is if there is any solution of that because I do not want the screws to fall down accidentally inside the slide and action part. Second does the x series optic slide fit the M17 because this one has the plate screw from outside and the rear site separate so you can keep it with a red dot
Without seeing it. I’d say take off the screws and use a wire brush and pipe cleaner to remove any residue on the threads. Locktite blue is a great thread clock so I don’t see that as an issue. Also, possibly there is something under the plate. When you remove it clean the base. Make sure to give the locktite time to harden. There should be nothing special to this system, so if it fails again I’d look at some new screws, check the threads to see if they’re a bit stripped.
I got a spent piece of brass trapped (and I suspect bent) in my M18 and the slide is seized up - it won’t move more than a quarter inch and never reveals what’s in the chamber Any ideas on how to force the striker plate off so I can get the extractor out which I suspect will free the slide? Pushing in on the pin and trying to push down on the striker cover doesn’t seem to budge
@@SIGMECHANICS this was an interesting problem I ended up solving - the M18 recoil rod is not round and must be inserted the right way - which it was - however I was using a third party DPM rod and somehow after 60 shots it rotated internally enough to cause a FTF. I thought that was the end of it but on the 63rd shot it failed to go into battery so I whacked the slide into battery and fired. The brass then became stuck internally and wouldn’t eject. I ended up getting a stronger person to help me and with three hands I managed to get the striker plate so I could remove the extractor. This allow me to open the slide but I still couldn’t remove it without whacking it with a rubber mallet while the takedown lever was down. It was a nasty problem I’ve never seen before despite owning 5 striker fire Sigs and putting tens of thousands of rounds through them.
Do the steps here apply to the p320 xcompact slide? I just picked one up and also received a zev stripped slide and need to move internals from oem slide to zev slide.
I’m not sure I understand. Do you mean can you swap the LCI slide to a non-LCI slide? Yes you can. If you mean swap an LCI barrel to a non/LCI barrel with the slide still cut for LCI, also yes (in a pinch) but you will have debris that will exhaust from the top so I don’t recommend it.
@@SIGMECHANICS I have an OEM slide with the LCI and an OEM barrel with LCI cut out. All the barrels I want have no lci cut. So my oem slide has the lci tab that would block a non lvi cut barrel from seating all the way when dropping it in the slide. If I remove the lci tab underneath my optic cover plate the slide will have a hole but not open thru all the way like the more common variation with the optic dust issue with vice versa setup ( non lci slide w/ lci cut barrel like you said.) If you were me, would you remove your lci from slide and run a non cut barrel, or just buy a different barrel with an lci cut to be totally correct with a functional lci? Sorry for the novel bud?
@@SIGMECHANICS I don't necessarily want to get rid of it, just thought i'd have to because I just found a few threaded barrels at a better price point without the lci cut but I'm going to play it safe and grab a threaded barrel with the lci cutout👍
For the most part yes, but a few changes exist. Watch this video for more detail… P320 - PRE v. POST UPGRADE ANALYSIS ua-cam.com/video/VmwpkJuIR00/v-deo.html
hopefully someone can help here. I have mushy trigger and I and see it have to do with the cap and the striker assemble not locking back. How do I fix that? Please
@@SIGMECHANICS Thank for the fast reply. I have been fiddling with it and I get the click now but before there was no trigger reset. I came to the conclusion in part because it was replacing the endcap that caused the issue but also when sliding it back into place it seems to depress the spring mechanism which did not reset if the cap was on. To be honest I am not sure what changed. Maybe the slide was not funny on as I was dry firing before to make sure it was all assembled but I may have solved it. I will have to take it to the range to be sure.
This is by far one of the best videos I have seen. I am Sig Classic armorer and feel confident I can disassemble my P320 now.

@@SIGMECHANICS I don't necessarily want to get rid of it, just thought i'd have to because I just found a few threaded barrels at a better price point without the lci cut but I'm going to play it safe and grab a threaded barrel with the lci cutout👍
Are the early ones identical?
For the most part yes, but a few changes exist. Watch this video for more detail…

hopefully someone can help here. I have mushy trigger and I and see it have to do with the cap and the striker assemble not locking back. How do I fix that? Please
Can you elaborate a bit? How did you come to that conclusion?
@@SIGMECHANICS Thank for the fast reply. I have been fiddling with it and I get the click now but before there was no trigger reset.
I came to the conclusion in part because it was replacing the endcap that caused the issue but also when sliding it back into place it seems to depress the spring mechanism which did not reset if the cap was on.
To be honest I am not sure what changed. Maybe the slide was not funny on as I was dry firing before to make sure it was all assembled but I may have solved it. I will have to take it to the range to be sure.
thanks from 2024
Do you have an email so I can send you some information off line ?
@peter villani. Sure it’s: sigmechanics@gmail.com
Lol the first time I disassembled my p320 my color blind ass thought the color coding on the recoil spring was rust
